Hey, i've been lately trying unsuccessfully to win a one-city challenge on Emperor difficulty. I do not want to go down to Monarch since i won the last 5 games on this level. I play large/fractal maps with Bismark; cultural victory is disabled. I must have tried around 10 games now on Emperor, the last 5 games i even used world-builder to give myself a super-capital. To no success. Mostly i lose to an AI winning domination in late game (9/10 games). I've tried gifting techs to always keep the two largest AIs in power-balance. But one always gets the upper hand and wins domination. If i do manage to stop domination (mostly by helping out actively in wars), i lose out on space-race since i have to build military instead of ship-parts. Any advice on how to manage the AIs?
